Title: System for the assembly of industrial installations on floating platforms.
IPC: B63B/
Filed: 1978-04-18
Abstract: The object of this invention is to achieve a system for the assembly of industrial installations, enjoying the advantages of installations assembled on marine platforms to enable their transportation by flotation, whilst at the same time not being affected by the actions of the sea and suffering practically no effects from earthquake activity.
